While ratings were predictably down for UFC on Fox 8, the event still ranked No. 1 among the 18-49 year-old demographic on Saturday night.
UFC on Fox 1 remains the highest rated event to air on the network, attracting 5.7 million viewers for a heavyweight title bout between Junior dos Santos and Cain Velasquez in November 2011.
UFC on Fox 8 took place at KeyArena in Seattle and was headlined by a flyweight title tilt between Demetrious Johnson and John Moraga. Johnson retained his belt by submitting Moraga with an armbar in the fifth round. The card also saw Rory MacDonald earn a unanimous verdict over Jake Ellenberger in the welterweight co-main event.
